Tank cleaning and disinfection
Ground and roof tanks drained, scrubbed, disinfected and rinsed, with the float valve and lid checked before refilling.
The water Kahramaa delivers to your meter is treated and tested. What happens next is up to the property: the tank it sits in, the pipes it travels through and the heat on the roof. We clean tanks, fit filters and protect heaters from scale.
Tanks, filters and scaleThe mains supply is desalinated, treated and monitored by Kahramaa. Most quality problems at the tap start after the meter: sediment and slime in a tank that has not been cleaned, a lid left open, or old pipes. Keeping the tank clean and filtering at the right point solves the large majority of complaints.
Follow the water from the street to the glass. Each stage is a place to check.
Ground and roof tanks drained, scrubbed, disinfected and rinsed, with the float valve and lid checked before refilling.
A sediment filter on the main line for the whole house, or a multi-stage filter under the kitchen sink for drinking water.
Scale shortens the life of heaters, mixers and shower heads. We flush heaters and fit protection on the line that feeds them.
The inlet is closed and the tank emptied. The last few centimetres, where the sediment lies, are removed by hand, not sent through your pipes.
Walls, floor and the underside of the lid are scrubbed to lift slime and scale.
The surfaces are treated with a chlorine solution and left for the contact time it needs.
The tank is rinsed until the water runs clear, then refilled.
Float valve, overflow, vent screen and lid seal are inspected. A lid that does not close is how most contamination gets in.
Fitted on the main line after the tank or pump.
Fitted in the kitchen cabinet with its own small tap.
Many homes use both: a simple sediment filter for the whole house, and a finer filter in the kitchen for drinking water.
A tank that overflows or a pump that will not rest is a leak question: see leak detection. Heaters damaged by scale are covered on the water heater page.
Every six to twelve months suits most homes. Clean it sooner if you see sediment at the taps, notice a smell, or find the lid was left open.
Not from that tank while it is empty. Cleaning one home tank usually takes a few hours. Where there is a ground tank and a roof tank, they are done one after the other so the interruption is shorter.
Yes. Ground tanks collect the most sediment because the supply arrives there first. They need safe access and good ventilation, which we check before anyone goes in.
For sand and rust, a sediment filter on the main line. For taste and drinking water, a multi-stage filter under the kitchen sink. For heavy scale, protection on the line that feeds the heaters.
It depends on the filter and on how much sediment your water carries. Sediment cartridges often last three to six months. A cartridge that has turned brown, or a drop in pressure, means it is due.
Yes, once the tank has been rinsed and refilled. A faint chlorine smell for the first day is normal and fades as the water is used.
